SPECIFICATION fo; 1 ing part of Letters Patent No. I710,183, datedSeptember 30, 1902. Application led September 13, 1901. Serial No.75,328. (No model.)

To all whom, it may concern;

Be it known that I, JACOB CLAUSEN, residing at Council Bluffs, in thecounty of Pottawattamie and State of Iowa, have invented certain usefulImprovements in Two Row Cultivators; and l do hereby declare that'thefollowing is a full, clear, and exact description of the invention,suchas will enable others skilled in the art to which it appertains tomake and use the same, reference being had removed. Fig. 2 shows adetail disclosing'l the mechanism for regulating the spread of thecultivator-frames. Fig. 3 shows a central sectional view of Fig. 2. Fig.4 shows a side elevation, with portions removed, of a two-row cultivatorembodying my invention, while Fig. 5 shows a rear view of the culti--vator embodying my invention.

My machine embodies, essentially, a central fiat bar D, which has itsforward end b bent at right angles, as is shown in Fig. l. Secured tothis barD at the fiat portion'b is a sheave-guiding bar C, preferably inthe form of an iron tube. This sheave-guiding bar C is fixed to the barD by means -of the U- shaped bolt. B, provided with suitable nuts 9, asis disclosed in Fig. 4. By this means the sheave-guiding bar C isadjustably secured to the central bar D, as the nuts 9 can at any timebe removed to permit a lateral adjustment of thissheave-bar C.

Secured to the main barD by means of the angular ends 1 l are thecounterpart L-shaped frame members A and A', secured by means ofsuitable bolts and nuts 1', as disclosed in Fig. 1. These L-shaped framemembers A and A are also preferably Iiat, and their forward ends areturned at right angles to provide a Hat surface, through which arepassed the U-shaped bolts B, held by the nuts 9.

Adjustably secured to the side portion of the counterpart frame membersA and A are the sockets 4. Centrally these sockets 4 are 'provided withthe set-screws 5, as is shown in`Fig. 1, while the end portions thereofare perforated to receive the axle-stems 3, as is shown more clearly inFig. 4, so that the [frame members A and A are pinched and bound againstthe axle-stems 3 by means of the vset-screws 5, so that theseWheel-supporting axle-stems may be slid backward or forward upon theframe members and can be almost instantly dissembled in packing orlshipping the implement.

Extending from the lower portion of these axle-stems are the` brace-bars4', which brace-bars are secured to the frame members A A by means ofthe clamp 7, held by suitable nut-provided bolts 8, as is disclosed inFigs. l and 4, so that these brace-bars may also be readily removed fromthe frame.

-The axle-stems 3 are provided with the wheels 2 2, so that the frame issupported in front by these wheels.

Secured to the central bar D at the rear is a collar 13, Within which isremovably held a pipe 15, this pipe being secured by means of theset-screw 14. Below and working within this pipe l5 is an axle 16,provided With the caster-wheel E. This axle 16 is held Within the pipe15 by means of the setscrew 17,which Works Within a suitable groovewithin the axle, so that this caster-wheel E is swivelly held Within thetube l5, as is usual in implements provided with threesupporting-wheels. The pipe or tube 15 may be raised or lowered, and theframe members A and A may be raised or lowered upon the axlestems 3, sothat the whole frame is vertically adjustable and may be raised andlowered.

Secured to the projecting end b of the central frame member D is theperforated bar c, provided with the openings e, and above is secured theplate c', held by means of suitable nut-provided bolts x', so that thefor- Ward bar portion b is clasped between the bars c and o.

Secured to the forward portion b of the IOO frame member D by means ofthe bolt 29, re-

ferring now to Fig. 1, is a draft-bar F, which is provided with thecentral perforations and to each end is further provided with openings,so thatv the nut-provided bolts 21 (shown in Fig. 4) may be placedwithin the baratthe ends. The bolts 21, passing through openings withinthe end of this bar F, holds two central stub-bars 22, which in turn bymeans of a bolt 23 aremovably secured to the ends a of the counterpartframe members A A. Centrally the bar F works above the end b and belowthe bar 32, which is secured by means of the bolts 29 and 31, as shown.By this means the draft-bar F may be adjusted sidewise to compensate thedraft inequalities when the implement is run on an incline.

To the bar F are secured suitable ears I-I H', to which are fastened theshafts 25 25, between which the central horse Works, this implementbeing intended to be drawn by three draft-animals.

Secured pivotally to the draf t-bar F are the levers G G, held by meansof the bolts 24, to the outer end of which levers are secured thesingletrees 30 by means of the links 28, While at the inner ends theselevers G are secured by means of the links 26 to the central singletree27, as shown in Fig. 1.

Secured to the forward pipe or bar C by means of the bars 40', which arebifurcated so that they Work above and below this tube C, are thesheaves or wheels 0, which ride against the pipe, as shown in Figs. 1and 4. Extending from these bars 40, there being four such bars shown inFig. 1, are the cultivator-beams M of any desired construction, whichare pivotally secured to the bars 40' by means of the bolts 5l and 52.These cultivator-beams are used in sets of twos and are united by thearch-bars N, as is usual in cultivator construction. To thesecultivatorbeams are secured the brackets 53 53, to which are secured theusual standards 54, provided with the shovels or cultivator shovels f.These cultivator-shovels form no part of my invention, as any suitablemake of manufacture may be used. These arch-bars N are secured to thecultivator-beams M by means of the U-shaped bolt fm, so that thecultivator-beams may be spread or brought nearer together, as maybedesired.

Secured to the bars 40/ are the telescoping bars 40, each provided withthe lip end 42, the remaining telescope-bar 4l provided with theupwardly-extending lip 42, as is shown in Fig. 2, so that these barsslide 011e upon the other-and may be lengthened orshortened. To unitethese bars, referring now to Fig. 3, I employ the bolts 45 and the bars43 43, between which the adjustably-secured bars 40 and 41 are held. Theupper bar 43 is provided with a bolt h, as is shown in Figs. 2 and 3,which supports a bar 39, secured to a lever K, as is shown in Fig. 1. Bymeans of these clamping-bars 40 41 the cultivator-beams M are adjustablyheld at their forward ends.

Secured to each cultivator-beam M is a chain S, which chain in turn isadjustably secured by any suitable means, such as a hook, to aperforated bar P, as is shown more clear] y in Fig. 5, and from this barP extends upwardly a chain R, working over a pulley p, which chain R issecured to an ordinary locking-lever T of any suitable construction, asis shown in Fig. 5, so that these cultivatorbeams, which slide upon theforward pipe C, may be raised and lowered to give the cultivator-shovelsf proper adjustment. In connection with the locking-lever T, I use theusual notched sector 56, from which extends a bar 57, supporting thepulley p, and a bolt n, holding the lever. Any suitable lever lnay beused.

Referring to Fig. 1, it will be noticed that secured to the perforatedbar c by means of the bolts 34 are the bars I I, to which are securedthe levers K K, so that these levers are pivotally as well as adjustably secured to the perforated bar c. To the bars I I are secured theconnecting-rods 39, secured to the adjustably-secured bars 40 and 41, sothat these levers K, in effect, are shifting-levers, by means of whichthecultivator-bars M M may be shoved from side to side. Theseshiftinglevers may be provided below with suitable foot-rests 35, as isshown in Fig. 1, so that the operator may throw these cultivatorbeamsfrom side to side by means of his feet or they may be operated by hand.It will further be noticed that these shifting-levers are connected bymeans of a bar 38, working within suitable openings y, so that inWorking one lever both cultivator-frames may be independently shifted.

In detaching the connecting-bar 38 each set of cultivator-frames may beindependently shifted.

To strengthen the structure, the central bar D is secured to the pipe Cby means of the rods 36, held -by the bolts 37, as shown in` Fig. 1.

The operator can adjust his draft-animals to the 'cultivator in shiftingvthe draft-bar F from side to side to adjust the track and equalize thedraft and then by means of the bolts 34 can adjust the shifting-leversK. The spread of the cultivator-shovels is next adjusted by means of theadjustably-connected bars 40 and 41 andthe U-shaped bolts B, while thevertical position is determined by means of the levers T.

Having thus described my said invention, what I claim as new, and desireto secure by United States Letters Patent, is-

l. The combination in an implement of the character described, of twowheel-supported axle-stems, of a four-sided frame vertically adj ustablysecured to said axle-stems a caster-wheel vertically adj ustably securedto said frame, a draft-bar laterally adj ustably se- IOO IIO
